ip_header wasn't 20 bytes on windows compilations for some unholy
reason. This restructures it to avoid the template and just use two
different structs for le/be with a condition_t for the ifdef, which
resolves it (and *also* apparently avoids the need for the pack).
Also add a static_assert to check the size.
Also do the same for ipv6.
Cast via an ordinary function pointer rather than a function pointer
reference to avoid the warning.
Also make the pointer in `Func_t` explicit rather than implicit (deduced
into the `Func_t` type) to make it clearer what is going on here.
Lots of tools struggle with non-default DNS port, so keep a listener on
127.3.2.1:53 (by default).
This required various changes to the config handling to hold a vector
(instead of an optional) of defaults and values, and now allows passing
in an array of defaults instead of just a single default.
It didn't do equality, it did "does the remaining space start with the
argument" (and so the replacement in the previous commit was broken).
This renames it to avoid the confusion and restores to what it was doing
on dev.
errno is only set if read returns < 0 and won't be set to 0 if read
succeeds, so we were bailing here frequently on successful reads
(whenever errno happened to be non-0).
This class is cursed, but also broken under gcc-12. Apply some lipstick
to get it moving again (but we really need to refactor this because it
is a mess).
* wintun vpn platform for windows
* bundle config snippets into nsis installer for exit node, keyfile persisting, reduced hops mode.
* use wintun for vpn platform
* isolate all windows platform specific code into their own compilation units and libraries
* split up internal libraries into more specific components
* rename liblokinet.a target to liblokinet-amalgum.a to elimiate ambiguity with liblokinet.so
* DNS platform for win32
* rename llarp/ev/ev_libuv.{c,h}pp to llarp/ev/libuv.{c,h}pp as the old name was idiotic
* split up net platform into win32 and posix specific compilation units
* rename lokinet_init.c to easter_eggs.cpp as that is what they are for and it does not need to be a c compilation target
* add cmake option STRIP_SYMBOLS for seperating out debug symbols for windows builds
* intercept dns traffic on all interfaces on windows using windivert and feed it into lokinet
we want to be able to have multiple locally bound dns sockets in lokinet so
i restructured most of the dns subsystem in order to make this easier.
specifically, we have a new structure to dns subsystem:
* dns::QueryJob_Base
base type for holding a dns query and response with virtual methods
in charge of sending a reply to whoever requested.
* dns::PacketSource_Base
base type for reading and writing dns messages to and from wherever they came from
* dns::Resolver_Base
base type for filtering and handling of dns messages asynchronously.
* dns::Server
contextualized per endpoint dns object, responsible for all dns related isms.
this change hides all impelementation details of all of the dns components.
adds some more helper functions for parsing dns and dealing with OwnedBuffer.
overall dns becomes less of a pain with this new structure. probably.
* make socket bind errors have a distinct message reported when caught using their own exception type
* omit printing banner in setup when we run from the lokinet executable (but not the liblokinet.so entry point)
Adds support for building Lokinet as a system extension, and fixes
various problems in the macos implementation found during development of
the system extension support.
outbound=:1234
outbound=0.0.0.0:1234
outbound=
outbound=0.0.0.0
now all default to use the inbound= IP. (If multiple inbound= IPs are
given, we raise an exception to abort startup).
Only applies to routers (since clients don't have inbound IPs), and
eliminates potential weird edge cases with local system IP and routing
shenanigans.
The general section comments contained all the descriptions for the
inbound/outbound settings, while inbound/outbound had no comment at all.
This moves the comments around to the individual settings, plus updates
some of the wording in the section.
We were failing when using `inbound=:1234`, rather than looking for a
default IP. This fixes it to still use the default IP, and change only
the default port.
Outbound behaviour should remain unchanged: i.e. `outbound=:2345` means
bind-to-wildcard-IP with a specific port.
Fixes:
- tighten reserved name detection to not match fooloki.loki, but instead
only match "foo.loki.loki" and "loki.loki" (and similar for reserved
name "snode.loki").
- IPv6 PTR parsing was completely broken.
- Added tests for the above two issues.
Cleanups:
- Eliminate llarp::dns::Name_t typedef for std::string
- Use optional return instead of bool + output param
- Use string_views; we were doing a *lot* of string substr's during
parsing, each of which allocates a new string.
- Use fmt instead of stringstream
- Simplify IPv4 PTR parsing
